The invention discloses a four-wheel drive type chassis structure for a robot. The chassis structure comprises a chassis mounting plate, and independent drive mechanisms used for driving the chassis mounting plate to move are mounted at the four corners of the outer surface of the top end of the chassis mounting plate. The four-wheel drive type chassis structure for the robot has the following advantages: firstly, the four independent driving mechanisms are mounted at the top end of a chassis mounting frame, so the same action of a double-structure system can be realized by utilizing the integral control of a main control system, and independent control of four transmission systems can be realized; and secondly, a speed reducer is arranged at the front end of a motor, a gearbox is arrangedbetween the speed reducer and a transmission shaft, large-load output can be achieved through double-stage speed reduction, the first stage is a standard planetary gear speed reducer to achieve speedreduction and torque increase of the initial stage, the second stage is a cylindrical gear speed reduction box to achieve speed reduction and torque increase of the second stage, and the reduction ratio of the two stages is multiplied to be the final output reduction ratio.

    本发明公开了一种机器人用四轮驱动式底盘结构,包括底盘安装板,所述底盘安装板的顶端外表面四角位置均安装有用于驱动底盘安装板移动的独立驱动机构。本发明所述的一种机器人用四轮驱动式底盘结构,一是通过在底盘安装架的顶端安装四个独立驱动机构,能够利用主控系统的整体控制来实现双结构系统相同的动作,并可以实现四个传动系统的独立控制,二是在电机的前端设置减速机,并在减速机与传动轴之间设置齿轮箱,通过双极减速,能够达到大负载的输出,一级为标准的行星齿轮减速机,来实现初段的减速增扭,二级为圆柱齿轮减速箱,来实现二级减速增扭,两段减速比相乘为最终输出的减速比。
